Working memory model

• Central executive


  Monitors incoming data, focuses and divides the limited attention and allocates subsystems to tasks

  Doesnt store info

  Modality free
• visuospatial sketchpad


  stores visual and spatial information

  Limited capacity

  Visual cache stores visual data

  Inner scribe records the arrangement of objects
• Episodic buffer


  Temporary store of info

  Integrates visual, spatial and verbal info processed by other stores and maintaining a sense of time sequencing

  Limited capacity (4 chunks)

  Links working memory to long term
• what part Is misunderstood

  Central executive is not very understood. Baddely said that it needs to be more clearly specified than just attention.
• Features of wwm

  Focuses more on the processes of memory than the structure

  Not linear
• Strengths

  • KFs phonological loop was damaged but his visuospatial sketchpad was in tact. Supports the idea that there are separate visual and acoustic memory stores
  • when Baddelys participants carried out a visual and verbal task at the same time their performance was similar but when having to do 2 verbal or 2 visual they struggled. This is because there is a competition for focus between the stores.
• Phonological store

  • receives auditory info
  • duration - 1-2 seconds
  • receives info from internal speech - we “hear” what we are thinking
• Articulatory loop

  • verbal rehearsal loop
  • holds words in an articulatory code where it repeats words over and over for as long as needed (acoustic)
  • capacity is determined by how long it takes to say something and not simply by the number of items like miller suggested
